Answer:
5:20
Step-by-step explanation:
In order to tell the time on an analog clock, we start by looking at the hour (shorter) hand. On this clock, it is pointing between the 5 and the 6, so we know it's a little after 5 o'clock.
Next, we look at the minute hand. Each number on the clock represents five minutes past the hour and the minute hand is pointing at the 4, so we know it is 4 x 5 or 20 minutes past the hour.
Therefore, we know that the time is 20 minutes after 5, or 5:20.
The time shown on the clock, obtained by reading the clock is; 5 : 20
How does one read a clock?Reading an analog clock involves looking at the positions of the clock's hands to determine the time.
The long hand, which is the minute hand of the clock is pointing at the number 4, which indicates that the time is 20 minutes past the hour, because each number on the clock face represents 5 minutes; (4 × 5 = 20). The direction the short hand, which is the hour hand is past the number 5, it indicates that the time is past 5 o'clock.
The position of the hour hand between 5 and 6 indicates that the time shown on the clock is 20 minutes past 5; 5 : 20

Answer:
5x - 15 + 2x + 90 = 180
180 since it's a flat line, and all the angles should add up to 180 which is angle AOB, 90 degrees is already given in the middle.
Simplify all the terms (The algebra portion)
7x - 15 + 90 = 180
7x + 90 = 195
7x = 105
x = 105/7
x = 15
now substitute in x for all these angles
2(15) = 30 degrees is the angle GOB
5(15) - 15 = 60 degrees is the angle AOF
60 + 90 + 30 = 180 degrees.
and x = 15

Answer:
$22100
Step-by-step explanation:
9/10 = 0.9
5/8 = 0.625
0.9 + 0.625 = 1.525
3 + 1 = 4
4 + 1.525 = 5.525
5.5 = $22000
0.025 = $100
$22000 + $100 = $22100
Use the incomplete reaction to complete the activity. Ba(ClO3)2 → ____ + 3O2 In one or two sentences, identify the type of reaction that is occurring and identify the other product. Based on the subscripts of the elements in the other product and the fact that chlorine has seven valence electrons, determine the number of electrons in barium’s (Ba) outer shell.
Answers
The missing product of the reaction is BaCl2 and we can see that barium has two electrons on its outermost shell.
The complete reaction is Ba(ClO3)2 → BaCl2 + 3O2. From the reaction equation, we can see that the missing product is BaCl2. The compound is composed of one barium atom and two chlorine atoms.
Since chlorine has seven valence electrons, it means that it requires two electrons from barium to complete its octet in BaCl2. This now means that barium has two electrons in its outermost shell.

in the function f(x)=6x^2-4, what is the value of f(-2)?
Answers
In order to find the value of f(-2), you can plug -2 wherever x is.
f(x) = 6x^2 - 4
f(-2) = 6(-2)^2 - 4
f(-2) = 6(4) - 4
f(-2) = 24 - 4
f(-2) = 20
Thus, the value of f(-2) is 20. Hope this helps! If you have any other questions related to this, let me know.
X: 3: 9/2 =15/4: 9/2 :Yask for the answer of x and y
Answers
Answer:
"X: 3: 9/2 =15/4: 9/2 :Yask" is difficult for me to understand.
The best I can find is x = 11 1/4 or 11.25
I'll assume:
X: 3: 9/2 means X/3/(9/2) and that is equal to 15/4/(9/2)
Step-by-step explanation:
X/3/(9/2) = 15/4/(9/2)
X/3/(9/2) = 15/4/(9/2) [Multiply both sides by (1/(9/2)
X/3 = 15/4
4x = 45
x = 11 1/4 or 11.25

x = 1/2 or x = 2/3
Step-by-step explanation:
6x^2 = 7x - 2
=> 6x^2 - 7x + 2 = 0
=> 6x^2 - 3x - 4x + 2 = 0
=> 3x (2x - 1) -2 (2x - 1) = 0
=> (2x - 1) (3x - 2) = 0
2x - 1 = 0

6x² - 7x + 2 = 0
Consider the factors of the product of the coefficient of the x² term and the constant term which sum to give the coefficient of the x- term
product = 6 × 2 = 12 and sum = - 7
The factors are - 3 and - 4
Use these factors to split the x- term
6x² - 3x - 4x + 2 = 0 ( factor the first/second and third/fourth terms )
3x(2x - 1) - 2(2x - 1) = 0 ← factor out (2x - 1) from each term
(2x - 1)(3x - 2) = 0
Equate each factor to zero and solve for x
3x - 2 = 0 ⇒ 3x = 2 ⇒ x = [tex]\frac{2}{3}[/tex]
2x - 1 = 0 ⇒ 2x = 1 ⇒ x = [tex]\frac{1}{2}[/tex]
